v2_10 实现值对象和具备类型的数据

v2_10 Implementing value objects and a typed data model 实现值对象和具备类型的数据

 

ex2_08

这部分解决两个问题

1.Employee如何作为一个值对象传入数据

2.如何将一系列通用的对象转化为定型数据模型

 

值对象一般不包含任何实施细节或商业逻辑,它只是一个简单的数据对象

 

即,从服务器取得的是XML格式的数据,如何转换成自定义的对象

这里就是简单的循环,将从服务端取到XML数据挨个放到Employee对象,由本例的employees取代上例中的employees

// event handlers -------------------------------------------
protected function employeeService_resultHandler(event:ResultEvent):void
{
	var employeeData:ArrayCollection = event.result.employees.employee;
	var employee:Employee;
	
	for each(var emp:Object in employeeData)
	{
		employee = new Employee();
		employee.firstName = emp.firstName;
		employee.lastName = emp.lastName;
		employee.id = emp.id;
		employee.title = emp.title;
		employee.email = emp.email;
		employee.managerID = emp.managerID;
		employee.department = emp.department;
		employee.location = emp.location;
		employee.deskLocation = emp.deskLocation;
		employee.city = emp.city;
		employee.state = emp.state;
		employee.countryCode = emp.countryCode;
		employee.directDial = emp.directDial;
		employee.hireDate = emp.hireDate;
		employee.evaluation = emp.evaluation;
		employee.postalCode = emp.postalCode;
		employee.phone = emp.phone;
		employees.addItem(employee);
	}
}

 

  

使用Flash builder的数据/服务 功能自动生成值对象

 

创建了值对象之后,XML数据转换过程还是一样,使用一个for循环来赋值
